Dear Felicity, here it goes.

I've watched you for 4 years. Always wondered what you were like ... what was going on in your mind all that time you were so quiet, just thinking, drawing in your notebook.

I should've just asked you, but I never asked you. So now, 4 years later, I don't even know you. But I admire you.

Well, this makes me sound crazy, but I'm okay with that.

So take care of yourself.

Love, Ben.

P.S. I would've said 'keep in touch', but unfortunately we never were in touch.
